Cyclopentanone

Description

1. Product Overview
Cyclopentanone is a high-purity cyclic ketone solvent and intermediate, essential for the synthesis of specialty chemicals, pharmaceuticals, and advanced polymers. Its primary industrial use lies in fragrance manufacturing, agrochemical production, and as a precursor for pharmaceutical active ingredients. The key value proposition is its exceptional solvency power and reaction selectivity, which drive higher yields in complex organic syntheses. Strategically, securing a reliable supply of Cyclopentanone mitigates production bottlenecks in high-margin sectors such as petrochemical derivatives and fine chemistry.

2. Key Specifications & Technical Characteristics

• Chemical composition: Cyclopentanone (C₅H₈O), CAS No. 120-92-3

• Purity grade: ≥ 99.5% (GC analysis); Pharmaceutical / Industrial grade available

• Physical form: Colorless to pale yellow clear liquid

• Key physical properties:

  • Density (20°C): 0.948 – 0.951 g/cm³

  • Refractive index (n²⁰/D): 1.436 – 1.438

  • Boiling point: 130 – 131°C

  • Flash point: 31°C (closed cup)

• Water content: ≤ 0.2% (Karl Fischer)

• Packaging options: 200 L net steel drums (190 kg net each), IBC totes (950 kg), ISO tank containers (20 MT)

• Shelf life: 24 months from manufacture when stored under nitrogen blanket in original sealed containers, away from ignition sources.

3. Core Industrial Applications

• Pharmaceutical synthesis: Key intermediate for manufacture of antihistamines, anti-epileptics, and muscle relaxants (e.g., cyclopentolate hydrochloride). Outperforms cyclohexanone in selectivity due to lower steric hindrance.

• Fragrance & flavor industry: Building block for jasmine-like odorants (e.g., methyl dihydrojasmonate) and macrocyclic musks. Provides superior olfactory stability compared to open-chain ketones.

• Agrochemicals: Precursor for plant growth regulators and fungicides. Enables higher reaction efficiency (reduced byproducts) versus acetone-based routes.

• Electronics & specialty coatings: High-purity solvent for photoresist strippers and precision cleaning. Low residue profile minimizes post-process defects.

4. Competitive Advantages

• Quality consistency: Batch-to-batch purity variance ≤ 0.1%, supported by ISO 9001:2025 and cGMP-compliant QC labs.

• Supply reliability: Dual-sourced manufacturing (China + Southeast Asia) with 8,000 MT annual production capacity; 99.5% on-time delivery rate.

• Logistics capability: Network of regional warehouses (Rotterdam, Houston, Shanghai) enabling 5-day lead time to major industrial hubs.

• Price competitiveness: Long-term fixed-price contracts available, hedging against petrochemical feedstock volatility.

• Sustainability: Recoverable via distillation (≥85% recycling efficiency); non-hazardous under transport classifications (UN 2245, Class 3) when properly packaged.

• Technical support: Full access to MSDS, stability studies, and reaction optimization data from in-house chemical engineers.

5. Commercial & Supply Information

• Minimum Order Quantity (MOQ): 20 MT (bulk liquid) or 4 IBCs (3.8 MT) for drummed product.

• Bulk 20MT loading capacity: 20 MT net per 20-ft ISO tank container (tare weight included).

• Container packing (drums): 80 drums of 200L (190 kg net each) per 20-ft general-purpose container = 15.2 MT net.

• Payment terms: LC at sight (irrevocable, confirmed) or TT 30% deposit / balance against copy of B/L for established buyers.
